Abstract-- Consider a multi-user private information-hiding
scenario in which two information hiders separately embed
correlated sources (S1, S2) into a common host source U
(covertext). The i-th information hider embeds the secret source
Si into the covertext U subject to a distortion constraint Di
(i = 1, 2). The outputs (stegotexts) are corrupted by a multiple
access channel attack WY |X1X2 . A sufficient condition (in single-
letter form) under which (S1, S2) can be successfully embedded
into U under WY |X1X2 is established.
I. INTRODUCTION
Information hiding is the means to embed a secret message
into a host message (covertext) so that the information hider is
able to transmit the information even though the transmission
